The cases involved 18 different countries and regions, said ministry spokesman Yao Jian.
Yao said the recently-concluded solar panel dispute with the European Union (EU) indicates that negotiation is the main tool to resolve future cases.
He said the 121 Chinese solar panel makers involved in the price undertaking deal with the EU reached in July accounted for 79 per cent of the country's solar panel exports to Europe.
Chinese solar panel makers should seize this opportunity to boost manufacturing ability and profitability, instead of following the old practise of excessive resource consumption and underselling, Yao said.
